[0085] According to the roof air conditioner installation device of the first embodiment of the utility model, the head 221 of the bolt 22 is limited in the groove 211. The roof air conditioner 10 can be installed on the composite material roof 1 by connecting the rod 222 of the bolt 22 with the nut 30 provided on the roof air conditioner 10. Compared with the prior art, in the roof air conditioner installation device of the embodiment of the present application, the head 221 of the bolt 22 is positioned by the groove 211 and the limiter, and the composite material roof 1 can be integrated with the installation mechanism 2 and then installed as a whole with the roof air conditioner 10. The connection position of the bolt 22 does not need to be welded, and the composite material roof 1 will not be burned, and the assembly convenience is improved, which is suitable for air conditioning installation on the composite material roof 1.

[0086] Preferably, the circumferential rotation of the head 221 of the bolt 22 is restricted so that the installation and positioning of the bolt 22 is more accurate.

[0087] See also Figure 7 and Figure 8 The nut 30 is fixed on the housing 101 of the roof air conditioner 10. Specifically, a mounting hole is provided at the bottom of the housing 101 of the roof air conditioner 10, a nut sleeve 102 is provided inside the housing 101 of the roof air conditioner 10, and the top end of the nut 30 passes through the mounting hole and is pressed into the nut sleeve 102. The nut sleeve 102 provides the installation strength of the nut 30.

[0088] The length of the groove 211 is greater than the dimension of the head 221 of the bolt 22 along the first direction, and the width of the groove 211 is greater than the dimension of the head 221 of the bolt 22 along the width direction (second direction) of the groove 221, so that before the bolt 22 is fastened to the nut 30, the head 221 of the bolt 22 can slide along the groove 221. That is, the precise position of the bolt 22 in the first direction can be adjusted. The first direction is, for example, the front-rear direction of the vehicle, and the second direction is the left-right direction of the vehicle.

[0089] Of course, according to different design requirements, the first direction may be, for example, the left-right direction of the vehicle, and the second direction may be the front-rear direction of the vehicle.

[0090] See also Figure 7 The limiting member includes a limiting plate 23.

[0091] See also Figure 7 The bolt connection assembly 20 further includes a spacer 24 for being arranged between the limit plate 23 and the nut 30. The spacer 24 is used to separate the limit plate 23 and the nut 30 so that the composite roof 1 does not directly contact the nut 30.

[0092] See also Figure 7 The bolt connection assembly 20 further includes a gasket 25 for cushioning between the stop plate 23 and the head 221 of the bolt 22, and the shape of the gasket 25 is adapted to the head 221 of the bolt 22. For example, when the head 221 of the bolt 22 is square, the gasket 25 is square; when the head 221 of the bolt 22 is hexagonal, the gasket 25 is hexagonal.

[0093] See also Figure 1 The plurality of mounting mechanisms 2 can stably mount the roof air conditioner 10 on the composite material roof 1. Figure 1 In the illustrated embodiment, six mounting mechanisms 2 are provided.

[0094] See also Figure 1 The plurality of mounting mechanisms 2 are arranged in two rows, and the two rows of mounting mechanisms 2 are arranged in the second direction on opposite sides of the composite material roof 1. Each bolt connection assembly 20 corresponds to a nut 30, that is, the number of fixing points of the roof air conditioner 10 is consistent with the number of bolt connection assemblies 20.

[0095] That is, the plurality of mounting mechanisms 2 on the left are arranged in a row, and the plurality of mounting mechanisms 2 on the right are arranged in a row, so that the fixing points of the roof air conditioner 10 are evenly distributed on the left and right sides, and the installation is more stable. Figure 1In the illustrated embodiment, four bolt connection assemblies 20 are spaced apart along the first direction on the left side, and four bolt connection assemblies 20 are spaced apart along the first direction on the right side, and the roof air conditioner 10 has eight fixing points (four on each side).

[0096] Some of the mounting mechanisms 2 are provided with a plurality of bolt connection assemblies 20. When the bottom beam is long, providing a plurality of bolt connection assemblies in the same mounting mechanism can improve the force uniformity of the mounting mechanism and avoid stress concentration. Figure 1 The bottom beam 21 of the mounting mechanism 2 located in the middle is longer, and the mounting mechanism 2 is provided with two bolt connection assemblies 20 .

[0097] The bottom beam 21 is an aluminum alloy profile, and the limit plate 23 is an aluminum alloy part. The bottom beam 21 and the limit plate 23 are both made of aluminum alloy, which is light in weight and is beneficial to the lightweight of the entire vehicle.

[0098] The mounting mechanism 2 is arranged at the periphery of the air outlet of the roof air conditioner 10. In this way, the mounting mechanism 2 does not occupy the arrangement area of ​​the air outlet of the roof air conditioner 10. In this way, the bolt 22 does not need to be assembled with the roof air conditioner 10 at the air outlet position, the structure at the air outlet of the roof air conditioner 10 can be designed to be simpler, and the air outlet position is easier to seal, which can improve the air outlet efficiency of the roof air conditioner 10.

[0099] See also Figure 2-5 , the bottom beam 21 is embedded in the composite roof 1. In this way, the height space of the bottom beam 21 overlaps with the height space of the composite roof 1, and the bottom beam 21 does not occupy the Z-direction (vertical direction) space of the vehicle alone, saving the Z-direction installation space of the vehicle.

[0100] See also Figure 2-5 The composite roof 1 includes a composite panel 11, a first decorative panel 12 attached to the top surface of the composite panel 11, and a second decorative panel 13 attached to the bottom surface of the composite panel 11, the thickness of the first decorative panel 12 and the second decorative panel 13 are both less than the thickness of the composite panel; the limiting plate 23 is attached to the top surface of the first decorative panel 12, the bottom beam 21 is embedded in the composite panel 11, and is sandwiched between the first decorative panel 12 and the second decorative panel 13.

[0101] The first decorative plate 12 and the second decorative plate 13 are used to decorate the composite material plate 11 to avoid the composite material plate 11 being exposed directly and causing unsightly appearance. The first decorative plate 12 and the second decorative plate 13 can be made of metal sheets, such as aluminum sheets. In addition, the first decorative plate 12 and the second decorative plate 13 can also clamp the composite material plate 11 and the bottom beam 21.

[0102] See also Figure 7 and Fig. 9The bottom beam 21 includes a top plate 212, a bottom plate 213, a first side plate 214 and a second side plate 215, the first side plate 214 and the second side plate 215 are arranged opposite to each other in the second direction, the top plate 212 is connected between the top side of the first side plate 214 and the top side of the second side plate 215, the bottom plate 213 is connected between the bottom side of the first side plate 214 and the bottom side of the second side plate 215; the top plate 212 is recessed toward the bottom plate 213 to form a recessed portion 2121, the recessed portion 2121 extends along the first direction, the internal space of the recessed portion 2121 constitutes the groove 211, the head 221 of the bolt 22 is clearance-matched with the recessed portion 2121, and the bottom surface of the head 221 of the bolt 22 is attached to the bottom wall of the recessed portion 2121.

[0103] Thus, the bottom beam 21 is in a "concave" shape and has good strength. The head 221 of the bolt 22 and the recessed portion 2121 are clearance-matched, which ensures installation reliability while retaining the adjustability of the subsequent bolt 22 in the second direction (the left and right direction of the vehicle).

[0104] The bottom wall of the recessed portion 2121 is horizontally arranged and the first side plate 214 and the second side plate 215 are vertically arranged, so that the bolt 22 is kept vertical, which is convenient for vertical installation of the bolt 22 and the nut 30 .

[0105] See also Figure 7 The lower surface of the limiting plate 23 is provided with a limiting protrusion 231 protruding toward the bottom wall of the recessed portion 2121. The limiting protrusion 231 extends into the recessed portion 2121. The limiting protrusion 231 is used to limit the head 221 of the bolt 22 in the vertical direction of the vehicle. The limiting protrusion 231 abuts against the gasket 25. In this way, the limiting protrusion 231 and the recessed portion 2121 jointly limit the head 221 of the bolt 22 to limit the Z-direction displacement and circumferential rotation of the head 221 of the bolt 22.

Compared with welding, the use of rivets 3 to connect the limit plate 23 and the bottom beam 21 can avoid burning the composite material top plate 1. In addition, compared with gluing, the connection strength can be increased. Compared with pre-embedded bolt connection, the process is simpler.

[0107] The limiting plate 23 can be rectangular and fits tightly with the top surface (first trim panel 12) of the composite roof 1, increasing the area of ​​the bearing surface, effectively ensuring the uniform transmission and diffusion of force from the fixing point of the roof air conditioner 10, and increasing the structural reliability.

[0108] See also Figure 1 A V-shaped groove 232 extending along the first direction is provided on the top surface of the limiting plate 23 corresponding to the bolt 22 and the rivet 3, so as to facilitate the subsequent positioning and drilling of the bolt 22 and the rivet 3.

[0109] Preferably, the rivet 3 is a high-strength alloy rivet, which reduces weight while enhancing the connection strength of the riveted position.

[0110] Sealant is applied around the head of the rivet 3. More preferably, a rubber sleeve can be put on the head of the rivet 3 after riveting to enhance the sealing performance of the riveted position.
